In a large mixing bowl, add room temperature butter, brown sugar and white sugar. Cream with a hand mixer or standing mixer with paddle attachment until smooth.
Add vanilla extract, applesauce, and peanut butter to the mixing bowl. Stir until combined.

Use an ice cream scooper to scoop balls of dough onto lined pan. Space about 2 inches apart.
Bake for 10-11 minutes or until cookies look barely set in the middle.
Remove cookie sheet from the oven. If you like flatter cookies, lightly tap the pan on countertop to help cookies spread slightly.
